Abstract (en)

A fuel injection system for an internal combustion engine, comprises: a pump comprising a pumping plunger which is driven, in use, to cause pressurisation of fuel within a pump chamber, an accumulator volume for supplying fuel to a fuel injector, a fuel passage providing fluid communication between the pump chamber and the accumulator volume, and an inlet control valve operable to control fuel flow into the pump chamber from a low pressure reservoir; wherein the inlet control valve is a latching inlet valve. The fuel injection system may be a hybrid fuel injection system, having a rail valve located in the fuel passage between the pump chamber and the accumulator volume. The latching inlet valve may be a two-way electronic latching poppet valve, and the rail valve may be a non-return valve. A method of operating such a fuel injection system for an internal combustion engine is also described.
